import java.util.Properties;



public class Config {
private static String CONFIG_FILE_PATH = "/config.properties";
private static Config inst;
private String ip;
private int port;
private Config(){
        init();
    }
public static Config getInstance(){
if(inst==null){
            inst=new Config();
        }
return inst;
    }
private void init(){
        System.out.println("init//////////");
        InputStream in=getClass().getResourceAsStream(CONFIG_FILE_PATH);
        Properties pro= new Properties();
try {
            pro.load(in);
            in.close();
        } catch (IOException e) {
// TODO Auto-generated catch block
            e.printStackTrace();
        }

        ip=pro.getProperty("ip");
        port=Integer.parseInt(pro.getProperty("port"));

    }
public String getIP(){
return ip;
    }
public int getPort(){
return port;
    }
}
